Gotta go for the big boys to try and take the room out of the equation...Used Pipedreams with 4 Sat subs would fill that room nicely. Silk dome tweeters are softer on the ears than horns plus they are pretty easy to drive at a db rating of over 90. With a room that big and beautiful Im going to assume they are within your budget.
Speaker suggestions for less than ideal accoustics
I live in a lovely timber frame home that works well for our lifestyle but presents challenges when trying to create a good audio listening environment. My great room has a wall of windows, tile floors (radiant heat), a large stone fireplace,28' ceiling peak, open to a loft area and open to the kitchen/dining area. The space is approx 1000 sq ft. I have listened in stores to some nice speakers (JM labs 816s, Def Tech 7004, Paradigm studio 100s, PSB T55,) but I know none of them will sound the same in my great room. Anyone ever faced this challenge and know if certain qualities in speaker designs lend themselves to this? I have learned a lot from this forum and wish there were more places to hear some of the equipment mentioned. BTW,this is for music listening only. Home theatre will have its own dedicated room in the basement where things can be built to suit
